The document explains the concept using a clear example where a sum is derived from its corresponding double (e.g., 5 + 4 = 5 + 5 - 1 = 9), helping students build mental arithmetic fluency. The content includes two sets of practice problems involving single-digit and small two-digit additions, followed by a comprehensive answer key to assist in self-assessment or teacher evaluation.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/exam/","Exam",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/adding-doubles-minus-1-grade-1-addition-worksheet/550697/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/adding-doubles-minus-1-grade-1-addition-worksheet/550697.png","ImageObject",300,407,{"name":42,"@type":43},"Aditya","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-11-04","2026-10-12",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",5,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What is the 'doubles minus 1' strategy?","Question",{"text":63,"@type":64},"It is an addition technique where you use a known double to solve a nearby addition problem by subtracting one, such as using 5 + 5 = 10 to find 5 + 4 = 9.","Answer",{"name":66,"@type":61,"acceptedAnswer":67},"Who is this worksheet designed for?",{"text":68,"@type":64},"This worksheet is designed for first-grade students to help them practice and improve their addition skills using specific mental math patterns.",{"name":70,"@type":61,"acceptedAnswer":71},"What is the result of 10 + 9 based on the provided methodology?",{"text":72,"@type":64},"Following the doubles minus one rule (10 + 10 -
